Lip and Chin Numbness After Chin Implants

Hello! Thank you for your question! Numbness after any surgical
procedure is expected for several weeks to months following. As the
nerves to the area are traumatized and will then experience a temporary
neuropraxia, a transient loss of nerve conduction. This usually
resolves over the next 6-12 weeks, but depending on the procedure
performed, sometimes much longer. Typically this should resolve by 1
year. As it goes past this date, the likelihood of the sensation
returning is small. However, it can take up to 2 years. If no return
from there, it is unlikely to return. It should be discussed that
persistent sensory changes may develop following any surgical
procedure.  If it worsens or persists - your implant may need to be adjusted.  Followup closely with your surgeon.The usual signs of the nerves regenerating and neuropraxia
resolving is itching, followed by a burning sensation and then
occasional sharp, shock-like pains. These will be normal to experience,
and actually a promising sign. Usually, normal sensation returns, but
is is also possible to have decreased sensation or even increased
sensation to the areas affected. Re-educating nerves postoperatively is
often helpful and will allow proper instruction for the affected
sensory nerves - methods include using different textures to the
affected areas when showering, bathing, applying lotion, etc. If
bothersome, there are some medications that may be helpful, including
Neurontin for pain for hypersensitivity. You can try various textures
such as washcloths, loofahs, cotton sheets, etc. Massaging the areas is
also beneficial for the incision to make the finest scar possible. The
last place to regain the sensation will be directly adjacent to the
incision/scar as the nerves will make its way from the periphery to this
location. If continual pain arises, evaluation is warranted. After
ruling out other causes, one rare explanation may be that a neuroma has
developed and may require surgical excision. This is very unlikely
unless a large sensory nerve has been transected inadvertently during
the procedure. Hope that this helps! Best wishes!

Not every patient notes numbness to the chin or lip after chin implant placement, but some do. Even in the minority of patients who do experience this numbness they will find that it will usually improve anywhere from a few weeks up to a couple months after surgery.

There are two major nerves that provide sensation to the lower lip and chin that exit the jaw bone just above the area where the chin implant is placed. Sometimes the nerves will be stretched a bit during the process of dissecting the implant pocket which can lead to the numbness. As long as the nerve wasn't cut, however, the feeling should come back.

Although we prefer for the sensation to be intact, the numbness can be quite normal after chin augmentation especially if combined with neck numbness.
AT about this time, as the nerves recover, you should be experiencing alot of pins and needles sensations. These will be aggravated by tapping over you jaw just below the corners of your mouth.
It would be very unlikely that both nerves were damaged on both sides of your chin.
Discuss your concerns with your surgeon, so that he//she can counsel and supervise your recovery.
